- Removed all references in UISL to reduce crashes

Fixed a bug where the button does not appear if not using controller.

Global memorial button will now show up when UICharacterPool is overwritten

Uses better way to handle screen listeners so mods overrides will no longer cause this mod to not work.

You may now character pool without loading the game (You must re-import them by loading the saves with the mod on, I did fail-safe old data to prevent creating blank characters by importing soldiers that haven't been updated)
